Warm relaxed digital coax

DH Labs has been my go to the past 3 or 4 times I've ordered cables.   Excellent quality for the $$$     

They usually have a sale on one or two product categories each month.   I bought a pair of Air Matrix Cryo at 20 or 25% off.  I also have the D-750 coax digital and the Mirage USB when they were on sale too.  All excellent quality 

I am going to order their Prelude speaker cables for my Forte IV soon.    

Snake River Audio is supposed to be warm and well made.

Is there a reason why you can’t use USB with the dac?

Because if you can, there’s a really nice Audience AU24SE+ USB cable on USAM right now.

Until recently I used the Acoustic Zen Absolute 75 Ohm Digital Cable with results similar to what you are seeking. There is at least one up for sale used. I am now using USB as my new streamer is limited to that medium. 

I can use USB.  I’ll check out these

suggestions. Thanks.
